Launching my blog with a walkthrough of virtme-ng: boot your kernel in QEMU, try cross-arch builds, run kselftests, and offload compilation to a remote machine. I'll be using virtme-ng on future posts.

- i don't have an UART-to-USB adapter

this is like super underwhelming but idk, i can't:
- learn c (easy but...)
- learn kerneldev
- learn how to port a device to postmarketos
- reverse engineer as necessary
without:
- working UART
- working android install
- working storage
all at the same time.
